OpenPIV-Matlab -- An open-source software for particle image velocimetry; test case: birds' aerodynamics
Hadar Ben Gida, Roi Gurka, Alex Liberzon
We present an open-source MATLAB package, entitled OpenPIV-Matlab, for analyzing particle image velocimetry (PIV) data. We extend the PIV analysis with additional tools for post-pr…
Unique flow features of the silent southern Boobook owl wake during flapping flight
Jonathan Lawley, Hadar Ben-Gida, Krishnan Krishnamoorthy +5
The mechanisms associated with an owls ability to fly silently have been the subject of scientific interest for many decades and a source of inspiration in the context of reducing…
Experimental study of the initial growth of a localized turbulent patch in a stably stratified fluid
Lilly Verso, Maarten van Reeuwijk, Roi Gurka +3
We present a laboratory experiment of the growth of a turbulent patch in a stably stratified fluid, due to a localized source of turbulence, generated by an oscillating grid. Synch…
Turbulent flow over a house in a simulated hurricane boundary layer
Zachary Taylor, Murray Morrison, Roi Gurka +1
Every year hurricanes and other extreme wind storms cause billions of dollars in damage worldwide. For residential construction, such failures are usually associated with roofs, wh…
